39, those wont work...The color is wrong. Green will reduce the voltage of the IR by .09% resulting in less than perfect control of the devices.

RTI uses Black connectors because they actually amplify the voltage by .03%

I have used blue (hard to find) which actually keep the voltages the same as whats fed in or out.

I have heard that red or yellow will not pass voltage at all under 5v so only use them for voltages over at least 10v

All the colors will work for AC and DC power




Kidding, Those should be fine
